. mats your blank diskette. This process takes
about two minutes. You know that the format-
ting is completed when the DOS prompt
appears again : SELECT ITEM OR RETURN FOR
MENU.
STEP 5
When the SELECT ITEM prompt appears, re-
move the newly formatted diskette and set it
aside. Then, re-insert the DOS Master Diskette
that you used earlier.
Loading the Program and Making the
Backup Copy
You are now ready to make the backup copy
of the program you wish to use. To do this,
first you will load the original diskette program
into your computer's memory, then you will
copy this information onto your formatted dis-
kette. The original diskette that you 'want to
copy is called the source diskette; the diskette
that will contain the backup copy is known as
the destination diskette.
STEP 1
Notice that item J on the DOS menu is the
duplicate disk function. To select this option,
type J and press RETURN.
STEP 2
Another prompt appears: DUP DISK-SOURCE,
DEST DRIVES? This prompt asks for the drive
number of the source and destination diskettes.
